1, is related to current and voltage. The constant sizzling sound comes from the inductor coil inside the mobile power supply. The mobile power supply needs to start the inverter circuit when the inverter circuit works to produce a certain frequency of alternating current, which belongs to the audio range, and needs to be converted by the inductor coil, under the action of the larger current, the coil will vibrate, and the generated sound will be transmitted, so there is a small squeak.
2, this situation is not normal, the general mobile power supply is not a soundYes. The reasons for this situation may be: 1, there may be water vapor on the mobile power motherboard, resulting in a slight short-circuit sound on the motherboard. 2, the mobile power motherboard in the process of boosting the sound, but the sound is usually very small, almost inaudible.
3, click the phone Settings page, select sound and vibration, and then select advanced sound Settings, you will see the system sound and vibration keys. After clicking, turn off the charging sound effect.
4, the circuit is designed with a switching power supply, in which the switching transformer will make a squeaking noise, which is caused by the magnetic core is not tight.Can solve the problem, after the replacement or can not be used is the mobile phone problem, need to repair. When charging, ding-dong ding-dong is the phone switches between charging and disconnecting two states.
2, this is often caused by poor data line contact, replacing a good data line can solve the problem, after the replacement or can not be used is the mobile phone problem, need to be repaired.
3, it means that the mobile phone charger is not connected well, you will re-check the charging head and data cable, and then connect it well for charging, if it can not be charged, it means that the data cable or power plug is broken, replace it with a new oneTo charge up.
The lithium battery of the charging treasure is the same as that of the mobile phone, most of them are 7V, such a voltage is unable to charge the mobile phone, so the charging treasure will increase the voltage to about 5V, this process requires the booster coil, the sizzling sound you hear is issued by it, and the better charging treasure may sound smaller. The inductance on the mainboard of the charging bank occurs in the high-frequency electromagnetic resonance, which has nothing to do with it.
Mi charger. If it's wireless, sometimes he makes a little noiseThe sound is very normal, so do not worry about it is also a normal phenomenon when he charges. If the sound is larger, you can go to the millet after-sales service to consult and check it.
If the noise is large, it may be the charger problem, you can change the charger to try charging. If the noise comes from the mobile phone, it may be a short circuit or leakage of the internal circuit of the mobile phone, or it may be a fault of the tail plug, and it needs to contact Xiaomi's after-sales service to repair the mobile phone to solve it.
The sizzling sound of the charging treasure is the low-frequency clutter generated during the operation of the switching power supply, which is heard by the human ear through the magnetic core vibration of the inductor.Normal switching power supply design will try to avoid this situation, hear such a sound is a product defect, generally does not affect the use. As Xiaomi is a big brand, the chance of such a mistake is not high. There are many imitation products of Xiaomi charging treasure on the market, and the quality is naturally less than the original products.
The green light of the millet wireless charger has been blinking because the automatic protection setting of the charger has detected a metal foreign body. When the charger encounters a metal foreign object near, it will automatically cut off the wireless charging,And continue to blink green light, power back to normal. It is recommended to check whether there is metal on the back of the phone or metal interference near the charger.
Although the green light flashing in most cases indicates that the charging is normal, there may be a problem with the connection between the charger and the device, or some small situation of the device itself. How to solve it? Try these steps! If the green light flashes, you can try the following steps: Make sure the device is tightly connected to the charger, adjust the position slightly, and you may see a change.
Xiaomi wireless charger A green light flashing usually means that it is charging, but the charging process can beThere may be some problems or anomalies. Indication that it is charging: When the green light on the Xiaomi wireless charger starts to flash, it usually means that the charger is charging the device. This is a standard charging indication that the charger has been properly connected and is transmitting power.
The reason why the green wireless charger lights up is that it is not plugged in steadily or the charging machine is damaged. The charger internal components are in poor contact, resulting in the charger can not be charged, check whether the charging loop is correct, check whether the electric vehicle plug and socket are in good contact, whether the wire is damaged, this is the first need to exclude the outsideFactor in.
If the indicator blinks, it indicates that the charging status is abnormal and wireless charging cannot be performed. The following exceptions may exist: The mobile phone is incompatible with the wireless car charging protocol. The phone does not support wireless charging.
Foreign body interference. Bex wireless charger uses micro high performance, when the use of the indicator flashes, usually because the distance between the charger and the device is too far or there is foreign interference.
